Then a shower distributes the water uniformly over the coffee dose. These models compress water by means of a pump which conveys cold water to a heat exchanger where the temperature reaches about 185 degrees F. In 1961 the development of the continuous flow machines replaced the previous ones. Later Achille Gaggia introduced the use of a large spring lever which gave the correct degree of compression to the water passing through the grounds. These machines brewed espresso by extraction pressure from the steam contained in the boiler. The first espresso machine was developed in 1901 by Bezzera.

This need is less marked in coffee beverages prepared by other methods such as infusion or percolators. Many types must be blended together in proportions according to the organoleptic characteristics of each. An espresso with a balanced taste cannot be obtained from one type of coffee.
